INGUBATGR Specicatin of Letters Patent.

Pat'fltd Fa, 10 1914 Application tiled May 8, 1918. Serial No. 766,438.

To all whom 'it may concern Be it known that I, HENRY F. FAUPEL, a citizen of the United States, residing at Raton, in the count-y of Colfax and State of New Mexico, have invented a new and useful Incubator, of which the following is a specification.

The present invention appertains to incnbators and relates more particularly to a hot Water system and Ventilating system therefor.

It is the object of the present invention to provide a novel and improved hot Water heating system for the incubator, which will serve to heat the egg or incubating chamber or compartment, so as to evenly distribute the heut and to maintain the said chamber or compartment at incubation temperature, in combination with a novel and improved system for supplying humidified air to the incubuting chamber, and for permitting the foul air to be discharged.

The present invention also comprehends the novel combination of the hot water heat;s ing and humidified air supplying systems, which shall enable the incubating chamber to be maintained at the incubation temperature, which shall permit fresh air to be furnished to all points of the incubating or egg chamber in abundance and without interfering with the incubation heat, and at the same time to permit the requisite amount of moisture to be distributed uniformly, the fresh air being merely warmed in order that the oxygen will not loose its incubation value.

With the .foregoing general objects outlined and with-other objects in view, which will be apparent as the nature of the invention is better understood, the present invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it

being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing from the spirit of the in vention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a longitudinal vertical section of the incubator, taken on the line 1-1 of Fig. 2. Fig. 2 is a horizontal section taken i on the line 2-2 of Fig. 1. Fig. 3 is a sectional detail illustrating a modifieatlon.

, .In carrying out the invention, reference being had in detail to the drawing, there is provided a norel form of incubator cese, which comprises the double walled bottom, top and sides providing dead air spaces. The bottom embodies the outer and inner walis 1 and 1` respectively: and the top embodies the outer and inner' walls 2 and 2', respectively: und each of the sides embodies the outer and inner walls 3 and 3', Vesper:-

ing the dead air spaces 4, 5 and 6, at the bottom, top and sides. ln constructing the case the outer walls 3 of the sides extend completely between the edges or margins of the outer walls 1 and 2 of the bottom and top. the inner Walls l and Z of the bottom und top fitting completely within the oufter walls 3 of the sides, and the inner walls 3 of the sides fitting between the inner walls lv und 2 of the bottom and top. Aithrough the particular construction as above described is of advantage and desirable, it is ,to be understood that the same muy be altered as may be necessary or desirable, Without departing from the spirit of the invention.

(lleuts 7 are secured to the inner feces of the inner walls 3 of the sides at a point slightly above the inner wall of the bottom. and on,the cleats 7 there is seated the e Y tray or shelf 8, which may be of any suite construction, and which i-s provided with air passages. The easing provides au incubat ing or egg compartment or chamber there-- in. at the bott-om of which, the egg way or shelf 8` is disposed.

Openings 9 are provided in the inner wall 1 of the bottom, and correspondin;r openings 10 are provided in the outer watL 3 of the said sides directly below the effigie of the inner Wall 2 of the iop. Ups'igminner and outer Walls of the said sides so as to extend completely between the inner wolle` of the bottom and top, a pair of cleats 1l being provided for each set of openings 9 and 10, so as to provide a flue or passage 1Q leading from the opening 9 to the opening 10. Thus` it will] be noted that the fines or passages 1Q lare shut off from the dead air spaces G- within the and provide for communication from c egg or incu- A baftor cham-ber to the ntnf @here i The hot water heating. .jstein embodies tively; the respective double Walls prcw'lel-V walls 3 of three sides directly adjoining the cleats or stripe ll. are secured between the an annular water tank 13 which jackets or encompasses the oil lamp or other heater 14, the said tank being disposed at the side of thc'ase which is devoid of the flues or passages 12. 'This side of the case, for convenience `will be termed the back, and the opposite side, the front. An endless water pipe 15 encircles the upper portion of the egg compartment, and extends around the corners between the sides and top, a supply pipe 16 passing through the back of the case adjoining the top and being connected directly'to the corresponding section of the pipe 15. A return pipe 17 passes through the back below the supply plpe 16 and extends across the egg chamber. The inner end of the return pipe 17 is attached to that section of the pipe 15 adjoining the front, and the outer end of the pipe 17 is directed downwardly, as at 18. The supply pipe 16 is attached to the upper end or top of the tank 13, while the outer end of the pipe 17 is attached to the front side of the tank 13 adjoining the bottom or lower end thereof. The supply pipe 16 is also preferably provided with a filling spout or opening 19, normally closed by means of a removable cap or plug 20, which permits the water conduits and tank to be filled, or replenished when necessary.

The Ventilating or air supplying system embodies an annular air chamber 21 encompassing and concentric with water tank 13,

the upper and lower ends of the air chamber and water tank are referably flush and the air chamber 21 pre erably snugly embraces the water tank 13. The air chamber 21 is also preferably provided with a spout or opening 22 at -its upper end, at a point diametrically opposite the point of attachment of the supply pipe 16 to the water tank 13, the spout or opening being normally closed by a cap or plug 23, which is removable. An air inlet funnel 24 is attached to one side of the air chamber 21 at a point slightly above the bottom or lower end, and depends or projects below the bottom of the case, so as to draw fresh air from below the case, it being noted that the case may be supported in any suitable manner, preferably by means of corner legs or standards, which need not be shown or described.

Within the egg chamber, there is disposed the rendless air pipe or conduit 25 which is disposed in a plane below the plane of the water pipe 15, but which is of smaller dimensions. The air pipe 25 is preferably concentric with the water pipe 15, and is provided with perforaticns throughout. The air supply pipe passes through the back of the case below the pipes 16 and 17, and is attached to the adjoining section ot' the air pipe 25, and to the side of the air chamber 21 adjoining the top or upper end.l The depending end 18 of the water return pipe 17 passes downwardly through the top or upper end of the air chamber 21 and then through the inner wall of the air chamber 21, as-

clearly seen in Fig. 1. Thus, the return pipe 17 passes through a portion of the air chamber, and somewhat serves as a partition between the inlet 24 and the outlet or supply pipe 26.

Suitable dampers may be provided for the fines or passages 12 and a suitable damper or regulator may be provided for the lamp or oil burner 14, the dampers being thermostatically controlled in order that both the heat and air supply may be regulated to a nicety and to this end, any suitable meansv may be employed. thel same not needing description at length or illustration.

'lh'e humidiiication ot' the air passing through theY air chamber 21 is accomplished by pouring water into the air chamber 21 to a level slightly below the end of the fun nel 2l attached to the air chamber, it being noted that the spout or /opening 22 permits ot' water being readily pourned into the air chamber. Water may be supplied at` the lower end of the air chamber by means ot' a t'ont or water receptacle 27 attached to the lower end of the air chamber 21 by means of a tube 28, a wick 29 passing through the tube 28 and serving to carry the water from the font to the lower end of the air chamber by capillary action. Either means may be employed for supplying water to the air chamber.

In operation, as the heat is radiated from the lamp or heater 14 to the water tank 13, the water will become heated, and the circulation of water will be established, the water passing upwardly through the supply pipe 16 around the two halves of the pipe 15, and back into the bottom of the tank 15 by means of the return pipe 17, so that a continuous circulation of the water is estab lished. The circulation of hot water through the erg chamber is such, that the heat will be e ectively and uniformly transmitted to the several parts of the egg chamber. The heatI will be transmitted from the water tank 13 to the air chamber 21, and as a result, the air will b warmed, the water taking up the greater portion of the heat,v thus preventing the excessive heating of the air. The air is admitted through the funnel or inlet 24 and circulates through the air chamber 21 to the pipe 26, then flows through the said pipe 26 to the distributing pipe 25 and out of the perforations therein to the egg chamber. The air in passing or circulating through the air chamber 21 above the water in the lower end thereof, will become saturated with vapor, so that the air will be effectively humidified or laden with moisture to more eectivel carry out the process of incubation. It will be noted, in thisy connection, that the water in the air tank 21 is heated by the Water tank 13, so that the vapor'ascends into the path of the air to be carried off thereby. The humidified air passes from the distributing pipe 25 over the eggs (not shawn) disposed on the egg tray or shelf, and then passes through the egg tray or shelf to the openings 9 and then out the flues or passages 12 through the openings l0 to the vatmosphere. In this manner, the circulation of air' t is properly established, humidified air being supplied in abundance, and the foul air being discharged or carried off to the atmosphere through the lues or passages 12. I

The hot water heating and air supplying systems have aninterdependence of operation, which is highly beneficial. It will be observed that the water tank 13 takes up directly the greater portion ofthe heat radiated from thel heater 14, the airv chamber 21 encompassing the Water tank 13 so as to somewhat shield the same, an'd in. order that the air may be warmed sufficiently. It will be noted Ithat the. hot Water return pi e passes through -the air chamber so as to acilitate the warming of the air and the proper circulation of the air through the air chamber. The hot water heating system serves to effectively heat the various portions of the egg chamber, the heat being evenly distributed and the egg chamber beA ing maintained at incubation temperature, the supply of fresh air being entirely' inde pendent of the heating system that is, the

supply of fresh air is not regulated in any manner by the heat, s'o that fresh air may be furnished to all'dparts to the egg chamber in abundance an Without interfering with r A ensue. Tlhere will be no danger of t e fresh' air becoming excessively or labnormall heated which would produce injurious e '45 fects, and furthermore, the heating and ventilation is such as not to chill the eggs or Aotherwise produce injurious effects.

Itis to be understood that one of the sides 3 will be in the form of a. door, so as to 50 swing open, which willV not affect the operation of the device as above described, when the said. side or door is closed, although it is to be understood that any ferm of door may. be provided for the case.

.Having thus described the invention, what y is claimed as new is In an incubator, an annular-Water tank, a heater disposed therein, an annular airchamber surrounding die Water tank and having su inlet above its lower end, an air pipe env 'L ing from the air Chamber into the cav a water conduit disposed within the cese and embodying a supply pipe and return pipe, the supply pipe being attached to upper end of the water tank, and the outer end of the return pipe extending downwardly through. the air and being attached to the lower end of the Water tank.
